This is a 45-45-90 triangle.
What is the measure of x?
72
x = [?]

Answer:
5*sqrt2
Step-by-step explanation:
It would be same because both sides are equal in length sinve it is a 45-45-90 triangle
Answer:
x = 7
Step-by-step explanation:
Since it is a 45- 45- 90 triangle then it is isosceles with the 2 legs congruent, both x
Using Pythagoras' identity in the right triangle
x² + x² = (7[tex]\sqrt{2}[/tex] )²
2x² = 98 ( divide both sides by 2 )
x² = 49 ( take square root of both sides )
x = [tex]\sqrt{49}[/tex] = 7
